In this study, we put the emphasis on why powder characterization is needed to solve unwanted granular phenomena of the material that stores hydrogen.
In this study, we suggest the digital twins approach coupled with Granutools instruments to improve procesess in the real production line.

In this article, we explain the importance of powder flow characterization for battery manufacturing using instruments such as the GranuDrum, the GranuCharge and the GranuPack.
In this article, we show how DEM simulations can help to better understand powder flow measurement and how to cross the bridge between the laboratory measurement and processes optimization in the production plant.
In this study, we highlight the advantages provided by producing composite powders made of sulfur and carbon black compared to the simple dry-mixed powder blend method for Sulfur Li-ion based batteries.
The impact of the powder mixing step for electrode manufacturing has been investigated for three powder blends made of the same composition of raw powders with different mixing times. The influence of the mixing time on the packing density of the powder blend is evidenced by the GranuPack.
